@deadweed52,
Seeded herb? Cut it immediately since seeding reduces the % of THC.
You can get good seeds from the black market. You don't need to seed your plants unless its primo herb and it would be easier to make cuttings and grow clones. That way you have exactly the same genetics. Seeds, like children may not be the same quality as the parent plants.
Get your hands on "the Cannabis Grow Bible, 2nd ed." by Greg Green.......READ IT!
I grow herb under the aegis of my state's medical marijuana laws. I won't let seeded plants survive a single day once I see that they are seeded. It reduces dramatically the quality of the buzz.
I just harvested over three dozen plants, since I am registered to grow herb for several other medical marijuana patients. I reaped about 30-40grams of manicured tops/plant that I started from another buddy's cuttings at the beginning of June.
Its not just getting good herb, but quality yield as well. I really love the quality of a Buddha's Dream strain I stumbled onto, but the yield is only about half of the Northern Lights strain I grow. So, I isolated a plant of each, forced them to turn male, cross-pollenated them and today collected the seeds from both to see what I get, hopefully the yield of Northern Lights with the sweet, flavorful kick of the Buddha's Dream.
btw get the book I cited. It is going to be the best investment you ever made.
